T all 'whomz't muy concern Be it known that I, Boro FISHER Mnn'rz,

a citizen o 'r the United States, residing at Northumberland, in thecounty of North-- umberland, State of Pennsylvania, have invented certain new and useful improvements in Vehicle-lVheelsWith Demo'untable Rims;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and 'use the same.

This invention relates to Wheels `for motor vehicles, especially to wheels adapted. to carry pneumatic tires and has for its' object the provision of a novel Wheel provided with a rim which is quickly and easily detachable and which embodies novel means whereby the parts are securely held in their inter-- loeked position.

Ain important object is the provision of a wheel and rim to which a tire maybe easily applied.

A further object is the provision of novel means whereby the Wheel and rim may be interlocked in one operation.

An additional object of the invention is' the provision .of a wheel and rim of this character which will be simple in construction, light in weight, strong and durable in use, eicient inV service and a' general im'- provement of thel art.

AOther objects' and advantagestwill become apparent during the course of the following description, accompanied by the illustrative drawings, in which- Figure 1 is an elevationlof my novel wheel, Fig. 2 is an enlarged sectional view through a portion thereof showing the'locking means in detail, Fig. Sis a similar View showing the locking bolts retracted to permit disengagement of the rim, Fig. 4 is a cross sectional View on the line 4%-4 of Fig. 1, Fig. 5 is a cross sectional view on the line 5--5 of Fig. 1, and Fig. 6 is a plan view of a fragment of the rim showing the connection of its ends, parts being broken'away to show the periphery ofthe vfelly.

Referring more particularly to the draW'y ing the numeral 10 designates the hub of my wheel which may be of any well known type or construction. Spokes 1.51 radiate from the hub 10 and engage at their outer ends in Vthe;v folly 18 upon whi'chis mounted a felly band 14. At spaced intervals along its periphery the felly band 14'is provided with spaced strips 15 having their inner opposing faces inclined as shown to forni dove-tailed sockets or pocket'sffor a purpose to be described. rEhe ends of the strips 15 are connected by beveledA strips 16. i

My nove detachable rim comprises anam n ular ring 17 the ends of which are securedtogether by a plate 18 riveted upon one end4 of the ring 17 and provided at its other end with holes adapted to engage studsfl carried by the other end of the ring 17. By

this construction it will be seen that the ends' of the rin-g 17 may be readily disconnected. Upon its inner periphery thering 17 is provided with tongues 20 conforming in' con'- tour to and adapted -to seat within the pockets formed by the strips 15 on the felly'bands'.

The .rim is applied to the felly band by sliding the tongues 20 between the strips 15 until the edges of the rim register withl the edges of the felly band 14, `whereupon the inclined endsI of the tongues 20 will engage they beveled strips 16.

In order that the rim may carry a tire I provide it with side anges 22 adapted to engagev the edges of a tire. The flanges 22 are reinforced adjacent the tongues 2() if desired. The folly 13, felly band 14.- and the ring 17 of the rim are provided with alined openings 2d for the insertion of the valve stem Q5 of the tire. The openings 24e are sufficiently large thatthe tire may be placed on or removed from the rim without danger of tearing loose the stem 25.v The forward edge of the rim is slightly smaller than the rear edge to facilitate placing a tire thereon. Q

In assembling the Wheel the plate 18 irs preferably disengaged from the .studs 1 9 and the ends of the rim are slipped one under the other so that the tire may be easily placed thereon with the stem 25 pass-` ing through the holes 24. The plate i8 1s then rengaged upon the studs 19 and thel 'In order that'the rim and felly may be Securely locked together, I provide novel cam actuated locking means to be described.

IA substantially U-shaped shield 26 formed preferably of steel pressed in shape isdisposed against one sideof the felly 13 with the outer periphery of the shield engaging the `inner periphery of the felly band 14. The'shield 26 is provided atintervals along its length with sockets 27 within which are .disposed radially slidablebolts 28 the inner ends of which are bifurcated for engagement with a camv locking ring desig- 'nated as a whole by the numeral 29. The felly band and the tongues 20 on the rim are v.provided with alined holes adapted for thereception of the bolts 28 when the bolts are protracted. This interlocked position is shown in Fig. 2 of the drawings.

The ring 29 is formed annular in one piece and has its periphery- 'formed to provide cam or wedging portions 31. Furthermore, at intervals the* ring 29 is provided with lugs or handles 32 extending inwardly through slots 33 in the inner portion of the shield 26.

' It will be seen that when the handles 32 are moved tothe right to the extreme ends of i the slots 33 the engagement of the outermost oted spring catch 37 is adapted to engage the enlarged head 38 of each arm 34 for. preventing it from swinging open. The shield 26 may be secured upon the felly by bolts or screws as desired.

When it is desired to remove the rim from the wheel it is necessary to release the catches 37, swing the arms 34 toward the hub, and force the handles 32 tothe left whereupon the cam portions of the cam locking ring 29 will allow the bolts 28 to retract thereby releasing them from their vengagement with the holes 30. The rim may then be removed.

My rim and shield are formed preferably of as thin sheet steel as is practical though I do not wish to limit myself to any specific 'form of-1naterial. VVnile I have shown the shield 26 and locking ring 2 9 as formedin one annular piece it will be understood that I may form them of asmany sections as I desire. A

From the foregoing description and a study of the drawing it will be apparent that I have thus provideda wheel having a rim `which is quickly and esily attached and debe securelyvlocked in place. i

n ein be readily' understood that I rgserve the right to make various changes 1n the form, construction, arrangement and combination of parts without departing from the spirit of the invention ory limiting the.

scpe of the subjoined-claims.

carried by said spokes, a removable rim slid-- able laterally onto said stationary rim and aving thus described my invention, I'

provided with openings alining with openings in said stationary rim, a channeled annular ring secured upon said stationary rim and provided with enlarged sockets, bolts slidable radially within said sockets and a locking ring disposed within said channeled ring and provided with cam surfaces engaging said bolts, whereby rotation of said locking ring will force' said bolts outwardly through the-alined holes in said stationary rim and said removable rim.

2. A vehicle wheel comprising a hub, spokes radiating therefrom, a felly'carried by said spokes, a felly band surrounding said felly, said felly band being provided with a, plurality of holes, wedge-shaped socket members on the outer periphery of said felly.

pins extending' across the bifurcations of said bolts and engaging the inner periphery of said locking ring, said locking ring be- 'ing provided with cam surfaces engaging said belts and said pins, and operating hanscv dles secured on said locking ring and eX tending inwardly through the slots in -said channeled ring whereby said locking ring may be moved circumferentially within said' carried by said spokes, a removable rim on said stationary rim,.both of said rims being provided with alined holes, a channeled ring secured on said stationary rim, a plurality of bolts slidable radially through said channeled ring, Aa locking ring vslidable circumferentially through said channeled ring and said wedge shaped projecprovided with cam surfaces engagin said bolts for moving ythem radially, hand es secured .on said locking ring 1nd extending through slots in said channeled ring, and

f means for holding said lhandles against movement retreating said bolts, said means Comprising arms pvoted upon said channeled ring and provided with recesses receivng the ends of -sad handles, and catches preventing swinging of said arms.

In testimony whereof I affix nfy signature, in the presence of two' Witnesses.
